MECHANICAL POWER.

SPECIFICATION forming part of Letters Patent No. 298,739, dated May 20,1884.

' Application filed March 6, 1884. (N0 model.)

To ctZZ whom it may concern:

Be it known that I, JAMES \V. ELLIs, a citizen of the United States,residing at Cameron, in the county of Milam and State of Texas, haveinvented a new and useful Mechanical Power, of which the following is aspecification, reference being had to the accompanying drawings.

My invention relates to a combined roomventilator and fly-hand; and ithas for its ob ject to provide a device of this character which shall besimple in its construction and thoroughly efficient and effective in itsopera tion.

with these ends in view the invention consists in the improvedconstruction and combinations of parts hereinafter fully described, andpointed out inthe claims.

In the drawings, Figure l is a perspective view of a ventilator and fanconstructed-in accordance with my invention. Fig. 2 is a longitudinalsection of the same, and Fig. 3 is a perspective view of the weightactuating the gear-wheels.

In the accompanying drawings, in which like letters refer tocorresponding parts in the several figures, A represents the floor of aroom, and B suitable standards for supporting the actuating mechanism,having a crossbar, 0, secured at its upper end, which is intended torepresent the ceiling of a room. A short distance from the supportingframe or beams B is secured an upright, D, which is provided at itsupper end with asuitable opening for the reception of a shaft, E, theother end of which passes through the beam B, and is loosely mounted toturn in a bracket secured to the side wall. Upon this shaft E, betweenthe beams B and D, is attached the fan or ventilator, which consists ofa series of radial arms, upon which is secured a covering of any shaft,G, the ends of which are journaled in a bracket in the side of the walland in the upright B, respectively.

H represents whirls or pulleys, which are secured to the ceiling of aroom and depend therefrom.

Upon either side of the shaft G are secured the ends of cords or ropesin such manner that when the shaft is revolved the unwinding of one willserve to wind the other. These cords pass through the pulleys or whirlsin the ceiling, and are each provided at their ends with rings for theattachment of a weight, which, when it is attached thereto, draws thecord through the pulley, and thus imparts motion to the gear-wheel F,which imparts motion to the fan-shaft through the pinion-wheel which isarranged thereon. It will thus be seen that to revolve said shaft it isonly necessary to attach the weight to the end of the cord, which inunwinding one cord serves to wind the other, so that when one cord hasbeen entirely unwound it is only necessary to attach the weight to theopposite cord, and vice versa.

It will be seen from the above description that I have provided, at aslight cost and with very few parts, a simple and effective device forthe purpose set forth. It will, however, be seen that the power may beapplied. to various uses-as, for instance, a crank may be attached tothe revolving shaft at one end, and

the other end to a churn, sewing-machine, or in fact for almost any workwhich only requires a light power to operate the same.

It will also be seen that by providing dou-.

' in suitable bearings and provided with apinion, of a gear-wheelsuitably mounted in bearings and adapted to mesh with said pinion, cordsoppositely arranged upon the shaft of said gear-wheel and passingthrough pulleys,

and a weight for operating the mechanism, 1 In testimony that I claimthe foregoing as substantially as set forth. my own I have heretoaffixed my signature in 2. The combination, with a shaft providedpresence of two witnesses. with a pinion and suitably-arranged fan, of ay 5 gear-wheel adapted to mesh therewith, and JAMES WV. ELLIS.

cords oppositely arranged upon the shaft of the gear-wheel, and adaptedto pass through Witnesses: pulleys, said cordsbeing provided at theirends 13. I. ARNOLD, with rings for the attachment of a weight, sub- J.M. TUCKER. 1o stantially as set forth.
